You also get the $10 per month HD ticket waived if you want to keep your existing old MySky box and pay for multi-room.
What if you want to do that but already have multi-room? (MySky plus a STB) Would the $49 still apply for me? and will the rental be the same?
And yea, you'll have to pay the $49 upgrade for the new box. It's just the $10 monthly HD content fee that will get waived each month with multiroom.
